To (12.1. whom 'it-may concem:

'Be it -known that I, HERMAN W. Eloi!- naiin'a citizen of the United States, resid-- ing at Venice, in the county of- Los Angeles and State of California, have inventednew and-useful Improvements in Electrical-Circuit Controllers, of which the following is a specification.

This invention relates to an electrical circuit controller; has for its object to provide an'iinproved circuit controller and adaptable to a wide range of uses, and particularly adapted for controlling circuits utilized for energization of operating or actuating mechanisms, sucl i .as switch-throwing and gateniovingineans. Corresponding to the principle of'the invention, the electrical-circuit is controlled, as toits utilization for ener ization purposes, by means energizedby t'ie electrical energy traversing the circuit; suitable inake-andl-break devices and apparatusv being operatively associated with an elec,

trical motive element, or prime mover, which performs the actuating or operating functions 'denianded of it in 'the specific use of the invention to which, in such particular case, the latteris adapted.

In the disclosure of the drawing, the circuit controller is illustrated .as combined with and controlli .1g switch-throv ing means or apparatus; so that the admission of electrical ener to the entirety, for a brief period of time, causes the throwing of the switch points from one to the other position, together with its prior release and subsequent locking.

In said drawing: Figure l is a transverse sectional View, partly in full lines of aportion lof a railway roadbed and switchlthrowing' means associated therewith; the latter means being shown as Ainstalled in the roadrespectively. The switch-operating means include a. prime or motive element C; and

4of the roadbed.

said switch-operating mea-iis comprises' and a includes the electrical circuit controller which constitutes the invention.

The switch-operating nieansA are, in the inain, inclosed 'within the casing e which is set into the road bed, beneath the level of the rails, and extends in part beneath one of the rails as d.

f designates a line connection with any suitable source of electrical energy; end g Vdesignates a ground for theelectrical circuit which includes theline ofV connection, f, the prime mover C and the other' features of the circuit controller and switch-operating means, which comprises a'movable elec-v tro -inagnet /L and a circuit makerandbreaker la.

The movable switchoints a andifare connected by a plate or ar 3 accommodated between the ties, such as 4', of the roadbed,Y

and resting upon the base-plate' connected witli'one or both of-tlie ra.ils," as at 6, and' provided with stops? limiting the endwise se.,

movements of the plate or bar 3' transversely S, and the plate or bar 3 is also bolted, as at i S, to a slide 9 within thecasingc, and supported upon a. bracket 10; the casing being provided with. an enlarged opening 11 permitting play of the connection at 8 in thev shifting of! the switch-points and movement of the-slide 9. Locking means m are associated with the slide 9,; and operating means n are operatively connected and associated with the slide 9 and with the vlockir'ig means m. f

A particular forni of provision, constiuction, combination, association and relative arrangement of parts, members and features of the switch-operating means, and the electrical-circuit controller associated with and comprised inthe saine, as shown in the drawing, is as follows :-At one side or end Eaclrof the switch-pointsv 'a and b is bolted to the plate or barB, as at of the casing e a small electric motor 12 isl installed; andthe drivev or arniatureislliaft 13 thereof is provided with a spu'rear 14' meshing with a larger spnrLgear 15' the short shaft 16 Jouriialed in' a bracket l)17 upon the frame or casing of the motor 12;

said motor 12 constituting the prime mover or motive element C. Projecting from one face of the spur-gear 15 is a wrist pin 183 projecting through an elongated slot 19 formed in one end portion'of a link arm' 20;

the other end portion of which'is pivotally '.A'relatively arranged, and, the linkarm 20 rotation 'of eachof t e gears 14 and 15 bediametrically, opposite studs'21- and 22 proper brac (et 10 in positionv for alternate re ristration with chambers 27 and 28 in the s ide 9. The bolt or end portio -the rigtht, as the drawing reads, and then to connected. as at 21, with the adjacent end of the slide 9. The slide 9 and gear 15 are so'` and opening 19 therein, together with the diameter of the gear 15 are of such proportion that a full rotation of the gear 15, by the gear 14, serves to reciprocate the slide 9 thro ing the switch-points a and b first to the le with the parts initially in position shown 1n the drawin and the direction of ing as designated bythe adjacent arrows. Upon the face of theI gearl opposite that from which thewrist pin 18 proJects, and at oints are disposed y seated relative to the wrist pin 18, and operatin in 'connection with a trip arm 23, pivotal y supported intermediate of its ends as at 24, and conibined 'with the locking means m', operatin in a manner hereinafter described; sai

Alocking means includin a 'slidinvbolt or pin 25, whichcarries' t e movable electro maignet at its lower end and at its uppei en rejects through an opening 26 in the pin 25 is guided by the bracket andlby a supplemental bracket. 29`beneath the bracket 10, and is provided with an upper and lower stop, 30'and" 31, respectively, which respectively abut against the brac et 10 and the bracket 29 in t erespectivel ward and downward movements of the sliding bolt or pin 25. The shorter ofthe trlp arm 23 is formed into a bifurcated head .32 which embraces the bolt .or pin andan expansive coiled spring 33 surrounds the bolt or in 25 between the stop and the hea 32. The bolt or pin 25 may be rovided with insulation, as at 34, beneath t e stop 31, insulating the bolt or pinabove the stop 31 from the current passing through the electro-magnet k.

The circuit maker-and-breaker in is arranged beneath the movable electro-magnet i, in. position to be affected by the latter.; and may comprise a knife switch 35;' the switch arm 36 of which is arranged to workI vertically and is provided with 'ahead or armature 37 arranged directly beneath the pole piece 38 of the electro-magnet lt. The switc arm 36 is normally maintained in lowered and switch-closing position by tension means or a s ring 39. lhe switch arm 36 has a range ci) pla'y which permitsl it to travel upwardly,` so that its armature 37 shall be in contact with the pole piece 38 when the electro magnet /L is in elevated position. The electrical path, designated at p, is from the line cnnection({, to and throu h the electric motor 12, to an throu h the 'circuit maker-and-breaker lc and to e ground y, as a niotcrcircuit; and from the line co nctin f, ,to and through electro-magnet and to the ground g," as an electro-magn circuit.

-The operation, method of use Vand adva: tages of the improved electrical circuit coi troller constituting the invention, and of tl switch-operating means A embodyin tl invention, as shown a`nd described, will l readily understood from the foregoing d scription, taken in connection with the a1 compalnyimgdrawing and the followin statement-With the parts in the positior shown in the drawing, electrical energy froi the line connection f which can be made i any suitable manner, passes through and en ergizes the electric motor 12, the circuit be ing' closed through the circuit maker-and breaker lc. The gear 15 is immediately ro tated, causing the disengagement of thi larger end portion of the trip arm 23 fron the stud 21 into the path of which latter th -former projects; and, the electro magnet i 'being at the saine time energized, the cir cuit through the same from the' line of -con nection f tothe ground f/ being at all times elcsed, and the electro inagnet being independentof thc circuit maker-and-breaker the armature 37 is attracted to thepole piece 38, breakin f the circuit through the circuit inaker-and-)i'eakeiand opening the circuit through the electric motor 12 to terminate action of the same during the fall of the bolt or pin 25 and the electro-magnet lz, permitted by the freed trip arm 23, and under actuation of the sprin 33, thus releasing the slide 9. The fai of the electromagnet 71,' and of the bolt or pin 25 bears down the armature 37 with its switch-arm Strandagain closes the circuit through the circuit inaker-and-breaker c, again energizing the electric motor 12, which turns the gear 15 until the wrist p'in 18 causes the link armi-2O to move the slide 9 to the right, throwing the switch,consisting of the switchpints a and 5. As soon, however, as the other stud, namely 22upon the gear 15, is brought to bear upon the trip arm 23, the electro-magnet 1L and bolt or pin 25 begin tol rise, and the switch-arm is again ,elevated byy the electro-magnet lz, through the armature 37 olf the former, andthe circuit through -the electric motor 12 isagain broken, sto

ping the rotation of the earvl. 'As t e trip arm 23 is givenV its fina actuation by the stud 22, it forces the bolt or pin v25, at its upper end, into locking engagement with the slide 9 in the chamber 27, acting through the spring 33 which yields to prevent binding or fracture of the parts. If now theline con- 1 neetion f be denergized, the electro'magnet It will be correspondin ly' denergized and the switch-arm 36 will i@ permitted to fall under pressure of the tension means 39, and the parts will be in :position for actuation of l latter'operatiom-or series of operation'spthe i stepsdzescrlbedqabove"in detail will b e`1 ".l y Pefted .with theexception thatl the trip aria 263'vsil lnitially .lexreleased from the stud d 2'2"'an {irially engaged to operate thelock' licontroller constituting the invention com-1 element in itself controlled by ing.Imaan.csf,` ahy-fthe sal- 1521.

It will be seen that theelectrical circuit prises controlling'elements or a controlling an element energized bythe electrical circuit,` and .also mechanically controlled in connection with A 2Q the. prime mover or motive element, such asthe electric mot-or 12, which' verforms the f work infquestion. Itvwill also e noted that the electro magnet h isf'controlled as to its field area., by the motiveelement C and the operative ,connection betyveen the ,same and 'the electro-ma net.
